Top 500 supercomputers
 
http://news.bbc.co.uk/1/hi/technology/10187248.stm

Who cares if 95% of the desktop market is taken by Windows.
Windows systems constitute as little as 1% of first 500 supercomputers:)

Good.

I guess that despite 95% the market being M$, 99.999% of the TFlops of computing power, are *nix...

I'm guessing the same people who care that SOME_PERCENT% of the "top 500 supercomputers" run Linux. Who cares what <SOME MACHINE YOU DON'T OWN> runs?

as the graph shows:)

How has this statistics been taken/made?

I don't know. I guess it's not difficult. Each time a supercomputer is ordered by a university/organisation, the specs (+OS ) are recorded (?)

Having looked at the FAQ, it seems that it works slightly differently. Each organisation who wants to have their supercomputer listed needs to submit the data.

This composition is limited to the top 500 list. I read somewhere that one single zombie network in some cases would enter the topp 500 list if it used all available power on number crunching. I can't remember where I read it, but with some multiple times 10.000 computers in one network, it seems plausible (to me). And that's only the infected machines. And there is A LOT of windows machines out there. So if you include the whole market (all desktop machines), I would guess windows would be superior again.

On another note, I wonder when we will see Sony playstation on the list. Some scientist found out that you could build a great super computer cluster for a fraction of the price if you made a cluster of PS3 running linux. :)

Not after recent PS3 updates - they disabled the possibility of running linux on it:)

IMHO, I think you've missed the point:) it's completely irrelevant. 90% of those top 500 supercomputers run linux because they want something rock-solid, secure and stable.
90% of the zombie supercomputers run windows because it's not secure, buggy and easy to hijack.

You can't compare those two categories of supercomputers, IMO.

Oh, thats right. Bastards.

Yes, I get that. I was just commenting on Alexvaders post, but perhaps I misunderstood him.

I wouldn't be so sure. How much computing power the world has, and what sort of systems it's on, is a question that I don't think has really been looked at.
IIRC on the Folding@Home stats the Linux client 'punches above its weight', (there are 9 times as many Windows clients which produce only 5x as much performance) perhaps because GNU/Linux is a common choice for dedicated folding boxes some people have. On the other hand there's no Linux GPU client yet (the Windows one does run under Wine but can conflict with other usage of the GPU). Easily most of FAH's power comes from GPU and PS3 clients.
That said, the Linux Folding@Home clients alone would make the Top500, ranking around 130th.

Hehe, give one casio calculator to each Chinese, and you have some flops right there! (pun intended) :P

Is the rate at which politicians change their mind measured in FLIP-FLOPS?
